Description

Bud thinning clamp for medium and low dry mulberry trees

Technical Field

The utility model relates to the technical field of agricultural tools, in particular to a pair of bud thinning pliers for medium and low dry mulberry trees.

Background

In order to obtain high-yield and high-quality mulberry leaves, the bud thinning of the mulberry trees is needed. The mulberry has redundant branches which are necessary for uniformly distributing and optimizing the population structure, and many branches can not obtain required nutrients and sunlight at bad positions, thereby causing energy waste in the competition with strong branches. Systematically thinning out buds to form mulberry trees, which is beneficial to producing more high-quality mulberry leaves.

When the new buds of the medium and low dry mulberry grow to 10-15cm, the weak or growing bud leaves are removed, 2-3 buds are selected from each branch to grow, and the reserved branch buds can fully utilize the illumination condition of the mulberry field. At present, the mulberry field branch thinning still needs manual operation, and the manual bud thinning is protected by gloves, but the hands of workers with large workload are easy to be injured; when the branch buds which are developed quickly and lignified are removed, the bark of the main branch is easy to damage due to breaking; manually thinning buds at densely developed mulberry fists easily damages branch buds which are originally reserved; some new buds in a germinating state are difficult to remove manually due to small volume, and need to be removed after a period of germination, so that the workload is increased.
